I am pondering about getting a new notebook, the one in question (Sony Vaio PCG-GRX570 with a nice big 16 inch screen) has a Radeon 7500 Mobility chip, others with less screen come with Geforce2go (or the Geforce4go versions). Should I go for the Radeon or is the Geforce so much much better...? I will use it mainly for OpenGL programming.
